Marine technology company Wärtsilä has announced it will supply seven thrusters for a new Wind Turbine Installation Vessel (WTIV) being built for Eneti.
The supply scope for the contract includes six Wärtsilä WST-32 thrusters which benefit from a modern electric steering system to lower the overall lifecycle cost, a high level of reliability and reduced energy consumption. Wärtsilä will also supply one of its WTT-36 thrusters. All seven of the thrusters comply with applicable environmental regulations with the use of Environmentally Acceptable Lubricants.
Following the installation, Wärtsilä’s retraction system, combined with an energy efficient 8° tilt, will provide the vessel with reliable station-keeping performance. The tilt will deliver an effective thrust that is up to 23% higher than non-tilted thrusters, while also reducing power requirements and fuel consumption. The retractable thrusters’ combined electric steering and retraction system save on space and weight and have been produced using fewer components to ensure reliability.
“In line with our commitment to environmental sustainability, our focus today is on highly efficient technologies capable of delivering excellent performance,” commented Emanuele A. Lauro, chairman and CEO, Eneti. “We are assured that the Wärtsilä solutions meet this requirement.”
The next-generation WTIV is being built by the Daewoo Shipbuilding & Marine yard in South Korea and features a Gusto 16000X design, advanced lifting capabilities and a high energy efficiency. The order was placed with Wärtsilä in October 2021 and the components are scheduled for delivery to the yard in the first quarter of 2023. The ship is expected to be delivered toward the end of 2024.
“Safety and reliability are central needs for modern jack-up WTIVs, and our thruster package is optimized to deliver them,” explained Roger Holm, president Marine Power and EVP, Wärtsilä. “Furthermore, by ensuring efficient free sailing and outstanding dynamic positioning, regardless of the sea conditions, we are contributing to the decarbonization of the maritime sector.”
